Effect of the quantity of COCs and the injection quality on embryo recovery after Intrafollicular Transfer of Immature Oocytes (IFIOT) Author(s): NICOLÁS, A. C. C. V.; FARIA, O. A. C. de; BORGES, M. S.; KUSSANO, N. R.; PIVATO, I.; MARTINS, C. F.; DODE, M. A. N. This study aimed to evaluate whether the quantity of cumulus-oocyte complexes (COCs) injected into the preovulatory follicle, along with injection quality, impacts the final embryo recovery. Immature... ... Repository: BDPA Publication year: 2024
The use of different progestin devices in ovarian stimulation protocol affects gene expression in sheep cumulus-oocyte complexes (COC). Author(s): BRAGANÇA, G. M.; BATISTA, R. I. T. P.; SOUZA, C.
